DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 421,909, dated February25, 1890. Y

Application tiled August 12, 1889. Serial No. 320,491. (No model.)

To all whom t may concern.-

Be it known that I, BERNARD IWI. CONNOR, of Vaukon, in the county ofAllamakee and State of Iowa, have invented a new and useful Improvementin Draft-Equalizers, which improvement is fully set forth in thefollowing specification and accompanying drawing, in which the drawingshows a plan view of my improved draft-equalizer.

My invention relates to improvements in draft-equalizers; and its objectis to provide a simple and easily-constructed device by which fourdraft-animals may be successfully worked abreast, three being on oneside of a pole or other central point and one on the other. Thesepositions are often highly desirable, by reason of the peculiar natureof the work to be performed. When this device is attached to a plow,only one animal is compelled to travel in the furrow, while the threeothers have the benefit of the unbroken solid surface of the land. v

The apparatus is equally applicable to harvesting machinery, and by aslight modiiication may be adapted for three animals.

The invention consists in the peculiar combination of a series of simpleand compound levers, as will be seen by reference to the accompanyingdrawing, in which-M A designates a pole or tongue, having a limb Battached thereto at right angles and secured by a brace C.

The compound lever D is pivoted to the short levers E and F and also tothe stay-rod G. The free end of this lever is attached to a tongue.

short lever F and also to the brace J. The opposite end of this brace isattached to an intermediate link K in the stay-rod G. The purpose ofsaid link is to render the rod partially flexible under the varyingaction of the levers D and E and the brace J. The singletrees L areattached to the doubletree M and the levers D and I by clevises or othersimple appliances.

l. A draft-equalizer havinga main Whitfietree I hinged centrallyapproximately to the rear end of a central pivoted link or lever F,

said lever F being centrally pivoted to one end of a lever I, incombination with a lever D, hinged to a link E, which connects it to thetongue A, with the brace O and stay-rod G, substantially as herein setforth.

2. In a draft-equalizer, the combination, with the short leverE, pivotedon the tongue, the long lever D, pivoted on the rear orouter end of thelever E, the short lever F, pivoted on the lever D, and the long leverI, pivoted on the short lever F, the said levers D, F, and I havingwhit'fletrees attached, of the rod G, connected at its front end to thelever E and at its rear end tothe limb B of the tongue and provided withthe link K at its central portion, and the rod J, connecting the saidlink and the adjacent end of the lever I, substantially as specified. Y

In testimony that I claim the foregoing I have hereunto set my hand,this 11th day of August, 1888, in the presence of witnesses.
